Remove MIPS architecture
The MIPS architecture port has been added 5+ years ago in order to support a Chrome OS project that ended up going nowhere. No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code and MIPS-specific hacks.
